5.1.1 Forms Dual Monitor Certification

Forms applications use Oracle Application Server Single Sign-On only for obtaining database connection authentication. Once this connection is made, interaction with Oracle Application Server Single Sign-On no longer occurs. Exiting a Forms application will not perform an Oracle Application Server Single Sign-On logout. Conversely, logging out of an Oracle Application Server Single Sign-On session will not terminate an active Forms session. The database session will exist until the Forms Runtime (e.g. frmweb.exe) on the server terminates, usually by explicitly exiting the form.

5.1.3 Focus Issues and FORMS_REJECT_GO_DISABLED_ITEM

The GO_ITEM Built-in is not allowed to navigate the cursor to an item that is currently disabled. Setting this variable to False restores the behavior found in earlier versions of Forms where this was possible. This variable should only be used for backwards compatibility and may be removed in a future version of Oracle Forms.

New code should avoid navigation to a disabled item. However, if an existing application already includes navigation to a disabled item, and if there is no issue, you can use FORMS_REJECT_GO_DISABLED_ITEM=FALSE. However if you encounter focus problems with FORMS_REJECT_GO_DISABLED_ITEM=FALSE, and FORMS_REJECT_GO_DISABLED_ITEM=TRUE causes errors in the same transaction, then you have to modify your code.

5.1.4.1 GET_WINDOW_PROPERTY Returns 0 on Microsoft Windows

GET_WINDOW_PROPERTY(FORMS_MDI_WINDOW,WINDOW_HANDLE) returns zero even with separateframe=true. Oracle Forms Online Help states that this should work on windows platform. This is incorrect as this Built-in does not support MDI.

5.1.4.2 Availability of JACOB Libraries for WebUtil

5.1.4.3 Java Related Dialogs and Microsoft Windows Are Not Read By JAWS

You need to add access-bridge.jar and jaccess-1_3.jar to CLASSPATH.

5.1.4.4 Location of JAWS Scripts

JAWS scripts are now installed with Oracle Forms. The location for these scripts is ORACLE_HOME/forms/ScreenReader/, and are also available at Oracle Technology Network (OTN) at http://www.oracle.com/technology/products/.

5.2 Configuration Issues and Workarounds

This section describes configuration issues and their workarounds. It includes the following topics:

5.2.1 EM_MODE Needs To Be 1 to Enable Grid Control to Collect Metrics

The EM_MODE parameter in formsweb.cfg needs to be set to 1 for Grid Control to collect metrics. This parameter is set to 0 by default. You will need to restart the Enterprise Manager Agent.

5.2.2 Grid Control Reports Forms 10.1.2.0.2 Targets as Down after Web Cache Is Disabled

After disabling Web Cache, Grid Control reports Forms targets as down, which is false. As a workaround, in the targets.xml file in %ORACLE_HOME%/sysman/emd, change the target property with the NAME="ServletUrl" to read from the HTTP listener port instead of the Web Cache port.

If you encounter a FORBIDDEN error when using One-Button-Run with any of the supported Browsers other than Internet Explorer, verify if 127.0.0.1 (localhost) is in the proxy settings for your browser. If 127.0.0.1 is not in the exceptions list, then add it. This ensures that the browser will bypass the proxy server.

The environment setting FORMS_RESTRICT_ENTER_QUERY has a default value of TRUE. This setting disallows users from using QUERY-WHERE functionality until it is set to FALSE.

5.2.5 PJC Wizard Now Part of Oracle Forms

With Oracle Forms 10.1.2 and higher, the Forms PJC Wizard is part of the standard Forms installation. The PJC Wizard works with JDeveloper 10g (10.1.2) that is part of Oracle Developer Suite 10g. For versions of JDeveloper that are obtained from OTN, the PJC wizard is available as a separate Jar file to download and place into your JDeveloper installation.

5.2.6 Exception When Clicking Other Items While Inputting Multibyte Characters

In CJK languages, the Forms client may stop responding when clicking another item while inputting text through inline IME. As a workaround, disable the inline IME. See section 4.10.2, "Inline IME Support" in Oracle Application Server Forms Services Deployment Guide. This issue will be fixed in a future patch set.

5.2.7 CLOB Data Cannot be Retrieved When Query Data More Than Max Width

When using Japanese NLS_LANG (JA16SJIS, JA16EUC etc.) if the queried CLOB data is longer than the maximum length (240 bytes by default) of the Text Item corresponding to this CLOB data, the query fails at runtime. The issue is that the CLOB data is correctly truncated with the maximum length of the Text Item (240 bytes by default) in English NLS_LANG, but not in Japanese NLS_LANG.

This issue may also raise error message "FRM-40505"or "FRM-92101" depending on your platform.

As a workaround, extend the maximum length of the Text Item to fit the length of the CLOB data.

5.2.8 FRM-92102 Existing Sessions Disconnect When User Added To JAZN

The FRM-92102 error appears and existing Forms sessions disconnect after adding a new user to JAZN (OC4J_BI_FORMS | Applications | formsapp | Security). Thus, if you're adding new JAZN users to the OC4J_BI_Forms instance, you should do this while no Forms session is running.

5.2.9 Monitoring CPU Usage and Response Time

On the System Component Tables in Enterprise Manager, the CPU and Memory statistics are collected every minute, by default. Note that this potentially can mean that any CPU spikes will not be displayed. In addition, if Forms server processes are dormant, awaiting client activity or requests, it is perfectly normal for the CPU usage to report 0.0%.

On the Forms Overview page, the CPU and Memory statistics are gathered each time the page is rendered when you click the Overview Tab or when you click the refresh icon next to the timestamp. However, due to an operating system restriction, if the Response Time from the Forms Servlet is less than 16ms, it will display as 0.00ms.

5.3 Documentation Errata

This section describes documentation errata. It includes the following topics:

5.3.5 Enabling Single Sign-On Description Assumes a new Application

In Chapter 6, the section titled "Enabling OracleAS Single Sign-On for an Application" describes correctly the steps to add this parameter to the configuration section of a chosen application. However, if you change an existing section such as the default, the steps are slightly different as the parameter already exists.In this case, Step 5 becomes is where you select the parameter and enter a new value.

5.3.6 Incorrect Key Mapping

In Section 4.11.1.2.1 of Oracle Application Server Forms Services Deployment Guide, the description for Mapping F2 is written as:

To map F2, change the default entry for F2, "List Tab Pages", to another key. Here is an example of the default entry:

113: 0 : "F2" : 95 : "List Tab Pages"

This must be explicitly changed to another key mapping such as the following:

113: 8 : "F2" : 95 : "List Tab Pages"

The last line should read as:

113: 8 : "Alt+F2" : 95 : "List Tab Pages"

5.3.7 Incomplete JVM Pooling Example

In section 7.5.12 of Oracle Application Server Forms Services Deployment Guide, there is a sample formsweb.cfg configuration. The last named section is written as:
